Airworthiness Directives; Bombardier Model CL-600-2C10 (Regional Jet Series 700 & 701) and CL-600-2D24 (Regional Jet Series 900) Series Airplanes

This document publishes in the Federal Register an amendment adopting airworthiness directive (AD) 2003-19-51 that was sent previously to all known U.S. owners and operators of certain Bombardier Model CL-600-2C10 (Regional Jet Series 700 & 701) and CL-600-2D24 (Regional Jet Series 900) series airplanes by individual notices. This AD requires repetitive detailed inspections for cracking or deformation, or pulled or missing fasteners, on the lower panel of the left- and right-hand main landing gear (MLG) doors, as applicable, and corrective actions if necessary. The actions specified by this AD are intended to prevent failure of the lower panel of the MLG door, the lower panel's departure from the airplane, and consequent damage to airplane structure, which could adversely affect the airplane's continued safe flight and landing. This action is intended to address the identified unsafe condition.
